Abstract
An electrode is formed on a substrate such as a varistor, a PTC ceramic, or a piezoelectric ceramic by coating a surface of the substrate with a combination of a metal source and a source of reducing carbon. The substrate and/or the combination is an absorber of microwave radiation. Irradiation with microwave radiation causes a carbothermic reduction to occur, converting the metal source to a metal electrode on the substrate.
